In a study of autonomic reflexes it was found that some produce a generalized, bilaterally uniform response whereas others have an asymmetric or laterality of action. Recordings from vertebral nerve fibers (mainly vasoconstrictors to forelimb muscles), right and left cardiac sympathetics, and renal nerves show that baroreceptors evoke a bilaterally uniform inhibition but chemoreceptors of the c...

In the chemotactic motion of Escherichia coli, switching transmembrane chemoreceptors between active and inactive states is one most important steps signaling pathway. We study effect this time-scale on performance cell. quantify by drift velocity Our extensive numerical simulations a detailed theoretical model show that as activity rate increases, increases then saturates. data also mean durat...

Motile bacteria seek optimal living habitats by following gradients of attractant and repellent chemicals in their environment. The signaling machinery for these chemotactic behaviors, although assembled from just a few protein components, has extraordinary information-processing capabilities. Escherichia coli, the best-studied model, employs a networked cluster of transmembrane receptors to de...
